ATLANTA, Ga. (WRDW) -- We've all heard of snakes on a plane, but how about spiders? A Delta flight from Baltimore to Atlanta was delayed Thursday morning, not by weather or mechanical issues, but an eight legged issue.

Traveling can be a real headache, and it certainly was for one flight coming into Atlanta. "Delta told us it's a mechanical issue, and they weren't sure when the plane was going to be ready but that we would all be re-booked," said one passenger, Aileen Carlucci.

Aileen Carlucci was all set to fly from Baltimore to Atlanta when she and her husband were told their plane was not going anywhere. "All of the excitement in Baltimore and Washington has been the Pope being in town. I did not expect the excitement of what happened to me on the Delta flight," she said.

The excitement, some fellow travelers, most passengers didn't even know about. "My husband and I went to go be booked at another counter, and when we did the ticketing agent said they had tarantulas on the plane and that was the reason nobody could get on to the plane," the passenger said.

A Delta representative tells us an employee saw a tarantula loose in the baggage carrier. The plane had traveled from Atlanta to Baltimore, and was returning back to Atlanta. They could not comment on how many spiders were on board the flight due to customer privacy. "The plane had some in the night before, someone had transported the tarantulas, they weren't sure how many had gotten loose, but they were loose!" Carlucci said.
